At 28, Alex Becker has managed to build a company with annual revenue of roughly $4 million and grow his own personal net worth to seven digits, and he's on a mission to help fellow entrepreneurs out, too.

In his new book "The 10 Pillars of Wealth," the tech entrepreneur and multimillionaire shares his experiences and those of fellow millionaires to create a road map for building wealth as an entrepreneur.

After he left the Air Force in his early 20s, Becker launched and scaled Source Wave, an SEO software company that currently generates annual revenue of roughly $4 million. The company took off, enabling him to grow his net worth to more than $1 million by age 24. Becker is also CEO of software company Market Hero.
